ABSTRACT OF THE DISCLOSURE A tube having two sets of diametricallyopposed holes formed adjacent each of its ends and a pair of V-shapedstiff wires each threaded from a hole at one end of the tube through twoopposed holes at the other end and into the hole at the one end oppositethe starting hole.

BACKGROUND OF THE INVENTION This invention relates to spindles and moreparticularly to spindles for rotatably supporting rolls of paper for usein high speed printing devices.

Teletypewriters, computers and other high speed printing machinesusually print on paper supplied from rolls rather than on individualpages. Typically rolls of paper are mounted on spindles which serve torotatably support the rolls and to properly position the rolls in theprinting machines. In the past the spindles employed in high speedprinting machines have been unnecessarily expensive because they havebeen comprised of complicated parts which are difficult to assemble.

SUMMARY OF THE INVENTION In the preferred embodiment an inexpensivespindle is constructed from a support member having at least one holeformed in it and a spring formed from one of the holes to the other forretaining rolls on the spindle.

DESCRIPTION OF THE DRAWING A more complete understanding of theinvention may be had by referring to the following detailed descriptionwhen taken in conjunction with the drawing wherein:

FIG. 1 is a front view of a paper spindle employing the presentinvention;

FIG. 2 is a sectional view similar to FIG. 1;

FIG. 3 is a view of a portion of the spindle shown in FIG. 1 in whichthe spindle has been rotated 45 and in which certain parts have beenomitted more clearly to illustrate certain features of the invention,and

FIG. 4 is a sectional view taken along the line 44 in FIG. 1.

DETAILED DESCRIPTION Referring now to the drawing wherein like referencenumerals designate like parts throughout the several views, withparticular reference being had to FIG. 1, there is shown a spindlecomprised of a support tube 11 having a plurality of holes formed in itadjacent each of its ends and four lengths wire 12 each passing from ahole adjacent one end of the tube 11 to a hole adjacent the other end.As is best shown in FIG. 2 the lengths of wire 12 actually comprise theends of wire springs 13 which are preferably shaped in the configurationshown in dotted lines in FIG. 2. The wire springs 13 are assembled bythreading them through diametrically opposed holes adjacent one end ofthe tube and then inserting the ends of the lengths of wire 12 inopposite holes of a pair of diametrically opposed holes at the other endof the tube.

The tube 11 may be formed from steel, brass or other suitable materialand the wire springs 13 may be formed "ice from any hard, stilt wiresuch as music wire. The V- shaped configuration of the wire springs 13prevents slippage of the lengths of wires 12 with respect to the supportmember 11. Of course, the lengths of wire 12 need not necessarily bejoined together in which case they should be secured against slippagerelative to the tube 11.

As is shown in FIG. 3 the pairs of diametrically opposed holespositioned at either end of the tube are preferably oiiset by an amountsufficient to allow one of the wire springs 13 to pass behind the otherin the tube 11. The offset of the pairs of holes may be varied toaccommodate any particular situation, for example, the various wiresprings may be positioned at spaced intervals with respect to each otheralong the length of the tube.

The tube 11 has a shallow groove 14 formed around its periphery and asnap ring 15 is mounted in the groove 14. The ring 15 serves to positionitems carried by the spindle relative to the ends of the tube 11 andrelative to the wire spring 12. Other locating devices such as flangesformed on the tube 11, pins through the tube etc. may be substituted forthe snap ring 15 if desired.

If the spindle 10 is used in a device requiring frequent removal of thespindle an end cap 16 may be inserted in each end of the tube 11 toprevent persons handling the spindle from injuring themselves on theends of the wire springs 12.

In use rolls of paper are placed on the spindle and the spindle is inturn mounted in a printing machine. The wire springs serve to locate therolls radially on the spindle and to prevent slippage of the rolls. Thesnap ring positions the rolls axially with respect to the spindle andtherefore, with respect to the printing machine.

Although only one embodiment of the invention is shown in the drawingand described .in the foregoing specification, it will be understoodthat invention is not limited to the specific embodiment described, butis capable of modification and rearrangement and substitution of partsand elements without departing from the spirit of the invention.

I claim:

1. A spindle for supporting rolls of paper and the like including:

a tubular support member extending the length of the spindle and havinga plurality of holes formed in it, and

a wire spring including an apex positioned within the support and twonormally straight lengths of wire each extending in bowed fashion fromthe apex out one hole in the support member and into another holetherein.

2. A support spindle including:

a hollow tubular member having a pair of holes formed in it adjacenteach of its ends, and

a V-shaped wire spring threaded from one hole in one of the pairsthrough both holes in the other of the pairs into the other hole of theone of the pairs and extending in bowed arches between the holes in theone of the pairs and the holes in the other of the pairs.
